random missed call (Pixel 6A)

[redbridge]

Hi,
my cousin is using Fongo and now in Hong Kong. She has the Pixel 6A and she almost always missed the call because the phone never rang. I tried to help her with whatever available on the internet and still could not figure out the reason. Here is a scenario

Two days ago.
(1) on WiFi, first call went through and the phone rang and she was able to answer. Tried to call again, and after 5 rings, it went to voicemail (her phone never rang but the missed call screen popped up right after). Tried one more time, same thing happened.
(2) turned off WiFI and used the local 5G.... same situation.... first call went through and the phone rang and she was able to answer. Tried to call again, and after 5 rings, it went to voicemail (her phone never rang but the missed call screen popped up right after). Tried one more time, same thing happened.

Today... on Wifi.... She missed 2 calls from someone (no ring) but the 3rd call rang but she was too late to pick up!!!

She set it the ring to "12" but the voice mail kicked in after 5 or 6 (maybe a default?)

PS: I don't want to ask her to reinstall the app since I do not know if she will be able to find the "app" due to the locale. Same reason for not upgrading the Phone OS because she is out of Canada right now.

This is easier for me to explain using a Windows PC example because I would otherwise have to look up free smartphone apps that are similar to WinMTR. (It's not as useful as WinMTR, and I'm not a fan of Zoho's privacy policy, but someone pointed out to me that ManageEngine Ping Tool app is free on smartphones, and it can be used to ping servers repeatedly. Possibly other free apps can do the same thing).


"Ping is a measurement of data packet transmission, and ping does affect delay or lag. All gamers know, almost inherently, that lag affects them negatively. A PC gamer will pound his or her keyboard in hope that a character will respond on his or her monitor, quickly, but when there's a delay or lag, reality doesn't meet expectation. A gamer can see this problem visually. Over VoIP, anything over 200-210 ms, you will typically start to encounter crosstalk due to increased delay, even if the untrained ear doesn't notice. All VoIP services are subject to the same scientific principles including the fact that speed of transmission affects delay. When pings (and especially) jitter are high, VoIP can be a pretty horrible experience . . . Anyone using any communication service (or even when playing online games or using other online services) should understand that the longer the path to the server being used, the greater the potential exists for a problem to occur somewhere along that path.

If you ever play an MMO or select an online game server, gamers almost always choose servers that are closest to them for the most responsive online gaming experience, for a very good reason.


Fongo Mobile's servers are in Southern Ontario. Fongo Mobile uses SIP protocol.
For jitter, ping, and traceroutes, test to 208.85.216.39

Anything over 200ms is unacceptable. You'll begin to encounter crosstalk, even if an untrained ear doesn't notice. So, if you're getting really high pings and jitter, you have a problem.

What you don't want to see is 40, 45, 50, 35, 500, 40, 30, 45, 700. That's bad jitter.
You want relatively consistent pings without a lot of variation.

Bad jitter can produce broken up audio or choppiness during phone calls. Severe jitter/ping spikes can cause calls to drop and for incoming calls to not be received. Ping affects delay from the time someone speaks until the time it's heard."


There are smartphone apps, such as Net Analyzer, that allow users to run ping tests to IPs, which may be a better idea to try since the problem is on a smartphone.

The difference, here, is that when you test on a PC, chances are you're not connecting to cellular data, unless you're using a smartphone as a Wi-Fi hotspot, which is necessary to help discover where the problem is if you're using cellular data when the problem occurs. The caveat is you may be incurring cellular data charges while testing or using up a limited cellular data pool while testing.


1.Use winmtr https://sourceforge.net/projects/winmtr//. Ping about 200 times.
When using WINMTR, look at the very last line or hop when checking your pings.

If you're on a Macintosh, maybe this helps: https://www.reddit.com/r/TagPro/comment ... tr_on_mac/

When using WinMTR, look at your average ping and then maximum ping. Although WinMTR doesn't provide a jitter value, you can get an idea of what yours is by subtracting maximum ping from your average.
Jitter is the difference between each successive ping.
The bigger the difference, the bigger the problem.

Same with ping, which represents lag or delay. The lower your ping and jitter, the better."

Outside of Canada, the app is called Fongo World: https://www.fongo.com/services/fongo-mo ... d-edition/. It's a paid app, and using it would require creating a new Fongo World account, which would be unrelated to her Fongo Mobile account. Also, since the server location wouldn't change (still located in Ontario), the situation wouldn't improve. Ideally, you'd want the servers to be located in Hong Kong.
